Notes: Sensor are supplied with #28 AWG stranded nickel plated copper, PFA insulated wire. For additional cable length, add required length
(in inches) to end of the model number and $0.80/ft to the price. For a phone plug, add “-PP” to the model number and $7 to the price. For
tighter interchangeability, substitute the thermistor part number from the table below and add the price listed to the sensor price.
Ordering Examples: ON-940-44004-40-PP, ON-940 molded tip thermistor sensor, 2252 Ω at 25°C, interchangeability of ±0.2°C, 1 m
cable with a phone plug, $43 + 7 = $50.
ON-940-44034-40-PP, molded tipped thermistor sensor with 5000 Ω at 25°C, interchangeability of ±0.1°C, 1 m (40") of cable with a phone plug
connector, $42 + 11 + 7 = $60.
